Description

On Chrome (desktop), the login form is perfectly centered (i.e. both horizontally and vertically).

On my real iPad mini (iOS 9) instead, it is vertically centered but not horizontally (i.e. it is left aligned).

Considering that I'm definitely not a CSS expert, I first thought I messed up with some CSS rule but then I replaced the RoundRect? with a Container and I've got what I was expecting: the login form perfectly centered.

Is this different behavior between RoundRect? and Container something expected?
